For a stationary object on the earth's surface the centrifugal force is given as o'r. if the object is set in motion eastward by an impulsive force derive an equation for the total centrifugal force acting on the parcel. 4 marks) a) b) from a) derive the components of the coriolis acceleration. c) if a baseball player throws a ball westward a horizontal distance of 100 m at 30 (8 marks) latitude in 4 seconds, by how much is it deflected as a result of the rotation of the earth? (ω= 7.29×10-s rads-')

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
